Technical Field

[0001] This utility model belongs to the field of yogurt preparation technology and relates to a high-efficiency fermentation tank for yogurt preparation. Background Technology

[0002] Yogurt is a sweet and sour milk beverage made from milk through fermentation using Lactobacillus bulgaricus and Streptococcus thermophilus. It is a popular fermented dairy product due to its rich nutrition and unique flavor. Compared to regular milk, yogurt is lower in fat, higher in calcium, and rich in vitamins B2 and B12, as well as trace elements such as phosphorus and potassium. The lactic acid bacteria in yogurt are beneficial to humans, stimulating gastric juice secretion to aid digestion, improve appetite and gastrointestinal function, and effectively prevent intestinal infections and enhance the body's immune function, thus offering numerous health benefits.

[0003] Yogurt fermentation equipment is usually a single tank. During the fermentation process, various parameters (temperature, raw materials, oxygen concentration, stirring speed, etc.) need to be controlled, screened and optimized. Therefore, the requirements for yogurt fermentation equipment are also high. Existing yogurt fermentation equipment often has a simple structure, which leads to problems such as low precision of parameter control and low degree of automation.

[0004] To address the aforementioned problems, this utility model proposes a high-efficiency fermentation tank for yogurt preparation. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a high-efficiency fermentation tank for yogurt preparation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency fermentation tank for yogurt preparation, comprising a plurality of fermentation tanks mounted by a mounting bracket, each of the plurality of fermentation tanks being equipped with a stirring device; the plurality of fermentation tanks being connected by a pipeline system; each of the plurality of fermentation tanks being correspondingly equipped with a monitoring device, the monitoring device monitoring the image, temperature, oxygen content, and pH value inside the fermentation tank; each of the plurality of fermentation tanks being correspondingly equipped with a controller and an operation panel; the stirring device, pipeline system, monitoring device, and operation panel are all electrically connected to the controller.

[0007] Furthermore, the stirring device includes a stirring motor and a stirring assembly installed inside the fermentation tank.

[0008] Furthermore, the stirring assembly includes a stirring shaft, stirring blades mounted around the stirring shaft, and a flexible sleeve mounted on the stirring blades.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A high-efficiency fermentation tank for yogurt preparation includes several fermentation tanks 2 mounted on a mounting frame 1. Each fermentation tank 2 is equipped with a stirring device 3. Each fermentation tank 2 is an individual unit, and each fermentation tank 2 can be used independently when different flavors or different processes of yogurt need to be fermented. Each of the several fermentation tanks 2 is equipped with a corresponding monitoring device. Each of the several fermentation tanks 2 is equipped with a corresponding controller and an operation screen 4. The stirring device 3, the piping system, the monitoring device, and the operation screen 4 are all electrically connected to the controller. The monitoring device monitors the fermentation status of the yogurt in each fermentation tank 2, such as yogurt fermentation images, yogurt fermentation temperature, yogurt fermentation oxygen content, and yogurt fermentation pH value. The above data is monitored in real time and the information is fed back to the operation screen 4 through the controller so that the operator can respond promptly.

[0023] In this embodiment, the stirring device 3 includes a stirring motor and a stirring assembly installed inside the fermentation tank 2. Each stirring motor on the fermentation tank 2 is electrically connected to a controller. The controller can control the starting and stopping times and stirring frequency of the stirring motor, thereby flexibly adjusting the stirring state required for the yogurt according to actual conditions. After the stirring device 3 has stirred the yogurt raw materials added to the fermentation tank 2 for a specific time and at a specific frequency, the stirring device 3 stops working. The yogurt raw materials need to undergo fermentation for a specific period, during which they cannot be stirred to avoid fermentation failure.

[0024] It should be added that the stirring assembly includes a stirring shaft, stirring blades installed around the stirring shaft, and a flexible sleeve installed on the stirring blades. Preferably, the flexible sleeve abuts against the inner wall of the fermentation tank 2, so that when the stirring device 3 stirs the yogurt or yogurt raw materials in the fermentation tank 2, the flexible sleeve can fully scrape off the yogurt or yogurt raw materials adhering to the inner wall of the fermentation tank 2.

[0025] In this embodiment, each fermentation tank 2 is equipped with a feed pipe 5, a discharge pipe 6, an air inlet pipe 7, an auxiliary pipe 8, a water inlet pipe 9, a water outlet pipe 10, a breathing pipe 11, and a sampling pipe 12. Each of these pipes is equipped with a solenoid valve 13, which controls the opening and closing of the pipes. Several feed pipes 5 are connected to a main feed pipe 14, several discharge pipes 6 are connected to a main discharge pipe 15, several air inlet pipes 7 are connected to a main air inlet pipe 16, several auxiliary pipes 8 are connected to an auxiliary main pipe 17, several water inlet pipes 9 are connected to a main water inlet pipe 18, and several water outlet pipes 10 are connected to a main water outlet pipe 19. Several fermentation tanks 2 are connected through a piping system.

[0026] In this embodiment, yogurt raw materials enter each fermentation tank 2 sequentially through the feed main pipe 14. According to the weight of yogurt raw materials required for each fermentation tank 2, the controller controls the opening and closing time of the solenoid valve body 13 on the feed pipe 5 of each fermentation tank 2 to adjust the weight of yogurt raw materials required for each fermentation tank 2.

[0027] In this embodiment, the fermentation agent for traditional yogurt is usually anaerobic bacteria. When other strains of bacteria are added to the yogurt, it is necessary to meet the gas culture environment requirements of different fermentation bacteria. Specific gases are introduced into the corresponding fermentation tank 2 through the main air intake pipe 16 and the air intake pipe 7, thereby meeting the needs of different strains. The main air intake pipe 16 is connected to a gas network pipe and can be a nitrogen source, oxygen source, carbon dioxide source, etc. The controller controls the opening and closing time of the solenoid valve 13 on the air intake pipe 7 of each fermentation tank 2, adjusting the content of the specific gas required by each fermentation tank 2.

[0028] In this embodiment, the auxiliary pipe 8 serves as a backup pipe for the fermentation tank 2. It can be used in conjunction with the feed pipe 5 to introduce other yogurt ingredients into the fermentation tank 2. Alternatively, it can be used with the air inlet pipe 7 to introduce additional air into the fermentation tank 2. When the fermentation tank 2 needs cleaning, it can also be used as a clean water delivery pipe. The required substances are input into the fermentation tank 2 through the auxiliary main pipe 17 and the auxiliary pipe 8. The controller controls the opening and closing time of the solenoid valve 13 on the auxiliary pipe 8 of each fermentation tank 2, adjusting the content of the specific substances required in each fermentation tank 2.

[0029] In this embodiment, the inlet pipe 9 and the outlet pipe 10 are installed on the fermentation tank 2. When a specific water source is required to match the yogurt raw materials, the main inlet pipe 18 delivers the specific water source into the fermentation tank 2 through the inlet pipe 9. The controller controls the opening and closing time of the solenoid valve 13 on the inlet pipe 9 or the outlet pipe 10 of each fermentation tank 2 to adjust the weight of the specific water source required in each fermentation tank 2.

[0030] In this embodiment, after the yogurt in the fermentation tank 2 has finished fermenting, it is collected through the discharge pipe 6 into the main discharge pipe 15, and the collection is finally completed. Since each discharge pipe 6 is equipped with a solenoid valve 13, when the yogurt fermentation in several fermentation tanks 2 is inconsistent, the discharge pipe 6 is closed through the solenoid valve 13. This ensures that the yogurt in each fermentation tank 2 is individually transported to different collection points through the main discharge pipe 15, avoiding mutual interference. The controller controls the opening and closing of the solenoid valve 13 on the discharge pipe 6 of each fermentation tank 2.

[0031] In this embodiment, each fermentation tank 2 is individually equipped with a breathing pipe 11, which is used to discharge carbon dioxide from the fermentation tank 2.

[0032] In this embodiment, each fermentation tank 2 is individually equipped with a sampling pipe 12. The sampling pipe 12 facilitates the sampling and testing of materials in the fermentation tank 2 at any time, and makes it easier for operators to adjust various fermentation parameters.

[0033] In this embodiment, the monitoring device includes a camera and a temperature controller installed at the top of the fermentation tank 2; and an oxygen content detector and a pH meter installed at the bottom of the fermentation tank 2. The camera, temperature controller, oxygen content detector, and pH meter are all electrically connected to the controller. The camera monitors the yogurt fermentation process in the fermentation tank 2 in real time, and displays the data on the operation screen 4, allowing operators to easily observe the fermentation data. The temperature controller monitors the temperature inside the fermentation tank 2 in real time, and displays the data on the operation screen 4. The oxygen content detector monitors the oxygen content of the yogurt inside the fermentation tank 2 and displays it on the operation screen 4 in real time. The pH meter monitors the pH value of the yogurt inside the fermentation tank 2 in real time, and displays it on the operation screen 4 in real time.

[0034] Yogurt ingredients are fed into fermentation tank 2 through feed pipe 5. Fermentation starter, sweetener, thickener, and other additives are fed into fermentation tank 2 through auxiliary pipe 8. A pH meter monitors the yogurt's pH value in real time, a temperature controller monitors the temperature inside fermentation tank 2 in real time, and an oxygen detector monitors the oxygen content inside fermentation tank 2 in real time. If the temperature controller detects a low temperature inside fermentation tank 2, the controller opens the solenoid valve 13 on the air intake pipe 7, allowing hot air to enter fermentation tank 2 through the air intake pipe 7. If the temperature controller detects a high temperature inside fermentation tank 2, the controller alerts the operator, who then switches from hot air to cold air and introduces it into fermentation tank 2 through the air intake pipe 7 to ensure the yogurt is at the optimal fermentation temperature. Similarly, if the pH meter or oxygen detector detects data that does not meet the optimal fermentation temperature, the controller adjusts the corresponding data flexibly to ensure the final yogurt fermentation temperature.

[0035] After the yogurt fermentation is complete, the controller activates the solenoid valve 13 on the discharge pipe 6 to collect the fermented yogurt into the collection tank for further processing. The controller then activates the solenoid valve 13 on the water inlet pipe 9 to allow purified water to enter the fermentation tank 2, and controls the stirring device 3 to clean the inside of the fermentation tank 2. After cleaning, the controller activates the solenoid valve 13 on the water outlet pipe 10 to remove wastewater from the fermentation tank 2. Finally, the controller activates the solenoid valve 13 on the air inlet pipe 7, allowing hot air to enter the fermentation tank 2 through the air inlet pipe 7, completing the drying process.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
